J Speech Lang Hear Res 2021 Apr 12:1-15. Epub 2021 Apr 12.

MTA-BME Momentum Language Acquisition Research Group, Eötvös Loránd Research Network (ELKH), Budapest, Hungary.

Purpose Impairments in statistical learning abilities of individuals with developmental dyslexia (DD) have been demonstrated in word segmentation and in visual artificial grammar learning (AGL) tasks, but so far, little attention has been devoted to the AGL abilities of this population in the acoustic verbal domain. This study aimed to test whether adolescents with dyslexia have difficulties in extracting abstract patterns from auditory sequences of nonsense syllables based on a finite state grammar relative to typically developing (TD) peers. We also tested whether incremental presentation of stimuli of different lengths (starting small) has a facilitating effect on learning complex structures in dyslexia (and in TD) as opposed to presenting strings in random order.

Accomplishment of one-step specific PCR and evaluated SELEX process by a dual-microfluidic amplified system.

Biomicrofluidics 2021 Mar 5;15(2):024107. Epub 2021 Apr 5.

State Key Laboratory of Analytical Chemistry for Life Science, School of Chemistry and Chemical Engineering, Nanjing University, Nanjing 210023, China.

One of the main obstacles for systematic evolution of ligands by exponential enrichment (SELEX) failure is the generation of a non-specific product, as selection-inherent amplification procedures tend to form by-products, which prevents the enrichment of target-binding aptamers. Herein, we reported a dual-microfluidic amplified system (dual-MAS) based on the real-time polymerase chain reaction (PCR) detection chip and the large volume PCR chip for one-step specific PCR and for evaluating the SELEX process. First, it is a simple method to accomplish analytical PCR and amplification PCR in one step, and the optimal number of cycles for generating the specific PCR product is the cycles when the slope of the linear amplification period of the real-time PCR curve begins to decrease.

Automatic Pulse Classification for Artefact Removal Using SAX Strings, a CENTER-TBI Study.

Acta Neurochir Suppl 2021 ;131:231-234

Brain Physics Lab, Division of Neurosurgery, Department of Clinical Neurosciences, Addenbrooke's Hospital, University of Cambridge, Cambridge, UK.

High-resolution, waveform-level data from bedside monitors carry important information about a patient's physiology but is also polluted with artefactual data. Manual mark-up is the standard practice for detecting and eliminating artefacts, but it is time-consuming, prone to errors, biased and not suitable for real-time processing.In this paper we present a novel automatic artefact detection technique based on a Symbolic Aggregate approXimation (SAX) technique which makes it possible to represent individual pulses as 'words'.

Animacy and animate imagery improve retention in the method of loci among novice users.

Mem Cognit 2021 Apr 9. Epub 2021 Apr 9.

Department of Psychology, Purdue University, West Lafayette, IN, 47907, USA.

Recently, researchers have identified word animacy as a strong predictor of recall. In contrast, the method of loci is an ancient mnemonic technique which takes advantage of highly structured encoding and recall processes alongside a strong imagery component to create easily remembered "memory palaces." The present experiments examine the combined effectiveness of these techniques: Experiment 1 (N = 154) demonstrates that the method of loci and word animacy have additive effects, while Experiment 2 (N = 200) demonstrates that the additive effect of animacy is likely related to both the animate nature of words themselves and animate imagery associated with them.

What Can Network Science Tell Us About Phonology and Language Processing?

Top Cogn Sci 2021 Apr 9. Epub 2021 Apr 9.

Department of Psychology, University of Kansas.

Contemporary psycholinguistic models place significant emphasis on the cognitive processes involved in the acquisition, recognition, and production of language but neglect many issues related to the representation of language-related information in the mental lexicon. In contrast, a central tenet of network science is that the structure of a network influences the processes that operate in that system, making process and representation inextricably connected. Here, we consider how the structure found across phonological networks of several languages from different language families may influence language processing as we age and experience diseases that affect cognition during the typical and atypical acquisition of new words, during typical perception and production of speech in adults, and during language change over time.

Active maintenance of musical and linguistic information as a function of musical experience.

J Gen Psychol 2021 Apr 9:1-18. Epub 2021 Apr 9.

University of Wisconsin Oshkosh.

Recent research suggests that linguistic and musical information are processed by shared working memory resources in non-musicians. However, it is still unclear how musical information is actively maintained by those with extensive musical experience. Some evidence suggests that those with musical experience may utilize distinct processing systems for the active maintenance of linguistic and musical information. Read More
